Abstract: A relay device includes: a first contact and a second contact; a driving mechanism; a first conductor; a second conductor; and a static relay and an electric heating element. The driving mechanism is configured to cause the first contact and the second contact to be close to each other or separated from each other. The first conductor is electrically coupled to the first contact. The second conductor is electrically coupled to the second contact. The static relay and an electric heating element are coupled between the first conductor and the second conductor. The electric heating element is disposed to allow heating of one or both of the first contact and the second contact.

Abstract: A vehicle includes a power storage device, a power receiving unit for receiving power for charging the power storage device from an external power supply, an illumination unit for emitting light to the power receiving unit in response to a transistor attaining an on-state, and stopping the emission of light and a microcomputer for controlling the transistor.

Abstract: A vehicle including a battery, a plug receiving portion for receiving a plug for supply an electric power to be charged in the battery or a plug for receiving an electric power discharged from the battery, a lid for closing the plug receiving portion and a light for illuminating the plug receiving portion. In the vehicle, when the state of the vehicle becomes a running mode indicating a state that the running of the vehicle is permitted, the light is turned off.
